Mr Bridgen, who is a member of Jacob Rees-Mogg’s European Research Group (ERG), warned the Prime Minister is now “so weak” that she “actually just moves in the last direction of someone that kicked her”.

It was revealed on Thursday that EU member states could abandon one of Europe’s ideological red lines in return for further concessions from Mrs May.

A potential deal is now on the negotiating table and will be discussed at a special meeting of all 28 EU leaders in Salzburg, Austria, next month.

This would mark the first shift in position from the EU’s chief Brexit negotiator Michel Barnier and the European Council.

Mr Barnier has continued to claim that Mrs May’s Chequers proposals would “undermine our single market” and insisted Britain cannot “cherry pick” at access of the single market.
